CULVERT.

Specification of Letters Patent.

Patented Oct. 7,1913.

Application filed May 17, 1913. Serial No. 768,347.

To all whom it may concern: v

Be it known that I, R BAZELL HIBBs, a citizen of the United States, residing at Lewiston, in the county of Nez Perce and State of Idaho, have invented a new and useful Culvert, of which] the following is a specification.

The device forming the subject matter of this application, is a culvert, adapted to be employed upon a highway, or under like conditions, for the purpose of carrying laterally, into the ditches, water which flows along the wheel ruts.

Oneobject of the present invention is t provide a culvert of the type described which may be fashioned at trifling expense from structural steel elements.

Another object of the invention is to provide a culvert of the type described, in

which the closure is held interlocked with the body portion of the culvert by novel means.

It is within the scope of the invention to improve generally and to enhance the utility of, devices of that type to which the present invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawing :-F igure 1 shows the invention in side elevation; Fig. 2 is a top plan; Fig. 3 is a transverse section on the line 3-3 of Fig. 1; Fig. tis a transverse section on the line 4{i of Fig. 1.

The culvert herein described is preferably fashioned from metal throughout, steel or iron being the chosen material. The culvert comprises a bottom 1 and side plates 2. The bottom 1 preferably is a channel member, and the upstanding flanges 4 of this channel member are attached by means of securing elements 3 to the side plates 2. Locking strips 5 extend along the side plates 2 adjacent the upper edges of the side plates. The locking strips 5 are held in place upon the side plates by means of securing elements 6. Interposed between the locking strips 5 and the side plates 2 are spacing members 7 which may take the form of washers mounted upon the securing elements 6. Thus, the locking strips 5 are held in spaced relation with respect to the side plates 2.

A closure for the culvert is provided, the same comprising a pair of stop strips 8 which may take the form of angle members. The horizontal flanges 9 of the angle members 8 extend transversely of the upper edges of the side plates 2, and are spaced apart, thereby to provide a longitudinal opening in the culvert, through which water may enter. The securing elements 10 pass through or engage the horizontal flanges 9 of the top strips of the closure, the securing elements 10 engaging bridges 11 which rest upon the upper edges of the side plates 2. The vertical flanges 12 of the members 8 overlap the outer faces of the locking strips 5. Each of the bridges 11 is equipped with depending portions 14 which engage between the locking strips 5 and the plates 2. The bridges 11, in practice, may consists of short sections sawed off from a channel member.

From the foregoing it will be seen that the closure for the culvert will be'readily mounted in place and be removed, the construction being such that the closure cannot shift transversely upon the upper edges of the side plates 2. Preferably, the side plates are of trapezoidal outline, so that, as clearly shown in Fig. 1, the bottom 1 of the culvert slants downwardly from one end of the culvert to the other, thereby giving suflicient inclination to the flow-line of the culvert, so as to carry the water laterally into the ditch.

Having thus described the invention, what is claimed is 1. A culvert comprising sides and a con-' nection therebetween; locking strips secured to and spaced from the sides; and a closure comprising top strips and bridges connecting the top strips, each bridge having a depending end engaged between one side and the adjacent locking strip.

2. A culvert comprising connected sides; locking strips secured to and spaced from the sides; bridges extended across the upper edges of the sides and provided with de In testimony that l-claim the foregoing as pending ends engaged between the locking my own, I have hereto aifixed my signature strips and the sides; and angle members. in the presence of two Witnesses.

each comprising a flange supported by and; RBAZELL I-IIBBS. secured to the bridges, and a depending WVitnesses:

flange overlapped upon the outer face of FRED E. BUTLER,

one looking strip. ALEX. KASBERG.
